I want to be a computer engineer. But there is no good university in our country for engineering, so I decided to study abroad. But there is no university in our country for engineering, so I decided to study abroad. If I can’t read, then there will be no more to see my family. My dad's age, he will retire some days later. Then my family will have to pass me near. Please help me. I'll be grateful to you..
